If you’ve been using OS X for any length of time now, you know the special joy of desktop “spaces,” what Apple calls its virtual desktop system. You can switch between them by hitting Command-Arrow (right or left) on your keyboard, or you can activate Spaces with the F3 key on most modern Macs. You can also reorder these Spaces around fairly easily.

This one’s for all you Macbook and Magic Trackpad users; you know who you are. Mac OS X comes with Mission Control, a way to see all the open applications running on your Mac. Typically, you can hit the F3 key to bring up Mission Control and see what’s what on your Mac.

Similarly, you can either click on any Desktop Space across the top of Mission Control, or hit Command-Arrow (right or left) to switch to different Desktop Spaces on your Mac. This makes it easy to visually keep things separate. Some folks keep their web browser in one Desktop Space, and their word processing app in another, switching back and forth as they need the respective apps.

If you’re using a trackpad to access your Mac OS X laptop, or you’re using a magic trackpad connected to your Mac desktop, however, there are a couple of cool trackpad gestures you can use to do the same thing.

Remember that the OS X Mavericks beta isn’t a final version—it’s meant to be used by developers to ensure that their software will work with Apple’s latest and greatest. With that disclaimer in mind, let’s check out yet another little feature in the beta.

Prior to OS X Mavericks beta, the Dashboard, loaded with useful widgets of all stripe, used to be limited to two states: disabled, or locked to the top left side of the Mission Control screen.

Now, however, with the advent of OS X Mavericks beta, that’s no longer the case. The Dashboard is now treated the same as any other Space when enabled. Here’s how to get it enabled, and then how to move it around.

Apple is reportedly gearing up to make big changes to iOS 7, changes so big that it’s had to pull engineers away from OS X 10.9 development to help get it finished for its release later this year. I’m just hoping that the Cupertino company adds some of the features included in the latest iOS 7 concept video below.

Designed by Federico Bianco, the concept adds almost every feature we’ve ever wanted in iOS, including quick message reply, quick settings, widgets, Mission Control, and lots more. Check it out below.
